<p> CS177 LAB 5</p><p>Before the Lab Study Chapter 5 of the textbook.</p><p>Setting up your Environment Go to your working directory in “data.cs.purdue.edu” and create a directory “cs177/lab05”. Refer to the first lab or the other handouts on the course page if you need to remember the steps to do so. Then start the IDLE Python Interpreter.</p><p>Exercise 1 Complete the following program to display the output expected by replacing every “?” string with an appropriate string or list function (e.g. s[0]). Do not use string constants (e.g. “Hello World”).</p><p># # lab5-1.py: # Complete the following program to print the desired output. # def Main(): s = "I love Python Programming." y = " Yes!" print() print("Char at index 10 of s:", "?") print() print("Chars 2 to 5 inclusive of s: ", "?") print() print("Last character of s:", "?") print() print("Length of s:", "?") print() print("s repeated 3 times:", "?") print() print("s concatenated with y:", s + y) print() #You are not allowed to just type in the new sentence, manipulate the given string s. print("I love Programming Python: ", "?") print()</p><p> l=["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"]</p><p> print("Weekdays:", "?") print() print("Weekend:", "?") print() print("Two weeks:", "?") print() print("Days of the week:") for i in range(len(l)): print("?")</p><p>Main()</p><p>This is the expected output:</p><p>Char at 10 of s: h</p><p>Chars 2 to 5 inclusive of s: love</p><p>Last character of s: .</p><p>Length of s: 26 s repeated 3 times: I love Python Programming.I love Python Programming.I love Python Programming. s concatenated with y: I love Python Programming. Yes! I love Programming Python: I love Programming Python </p><p>Weekdays: ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday']</p><p>Weekend: ['Sunday', 'Saturday']</p><p>Two weeks: ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday']</p><p>Days of the week: 0 : Sunday 1 : Monday 2 : Tuesday 3 : Wednesday 4 : Thursday 5 : Friday 6 : Saturday</p><p>Save the program in cs177/lab05/mystring.py. Exercise 2</p><p>Write a program that will generate 5 random sentences. The random sentences will be built using one component from each of the following lists:</p><p> subjects + verbs + objects + endings</p><p> where:</p><p> subjects=['I','You','Bob','John','Sue','Kate', 'The lizard people'] verbs=['will search for','will get', 'will find','attained','found', 'will start interacting with', 'will accept','accepted'] objects=['Billy','an apple','a Triforce', 'the treasure','a sheet of paper'] endings=['.',', right?','.', ', like I said.','.',', just like you.']</p><p>(Lists based on the sentence generator in http://pastehtml.com/view/1c0gckz.html)</p><p>You can use the function:</p><p> from random import *</p><p> s = choice(subjects) print s</p><p> where choice will choose a random component from the sequence “subjects”.</p><p>Your program should print 5 random sentences. </p><p>Example: >>> Sue will accept a Triforce . I attained a sheet of paper , like I said. Sue accepted the treasure . John will get the treasure , just like you. Kate will get Billy , just like you. >>></p><p>Save the program in cs177/lab05/sentences.py. Exercise 3</p><p>Given the following lists of colors and fruits, write a program that generates all possible combinations. Hint: Use two nested for loops.</p><p> fruits = [ "apple", "strawberry", "banana", "pear", "watermelon", "tomato"] color = ["green", "red", "blue", "orange", "pink", "violet"]</p><p>Example output:</p><p>>>> green apple red apple blue apple orange apple pink apple violet apple green strawberry red strawberry blue strawberry orange strawberry pink strawberry violet strawberry green banana red banana blue banana …</p><p>Save the program in cs177/lab05/combinations.py.</p><p>Turnin your project Run PuTTY and login to data.cs.purdue.edu. </p><p>Turn in your lab by typing: cd cs177 turnin –v –c cs177 –p lab05 lab05</p><p>(Remember that the final “lab05” is the name of your folder.)
